GCL SI Leads Drafting of Testing Standards for 3-Terminal Tandem Cells

PV module manufacturer GCL SI, together with Soochow University and Yangzhou University, has initiated drafting group standards for testing and performance verification of 3-terminal crystalline silicon-perovskite tandem solar cells.

GCL SI said that 3-terminal perovskite tandem technology based on back-contact (BC) cells currently faces industrialization challenges due to a lack of unified testing standards, leading to poor data comparability and inconsistent performance evaluation. The proposed standards will address issues such as unique electrode configurations, spectral mismatch, and stability testing by defining testing procedures, parameter definitions, and data processing rules.

The initiative also introduces a tiered testing framework covering laboratory R&D and industrial verification, aiming to improve data credibility and support the mass production of 3-terminal tandem cells.

Recently, GCL SI, together with Yangzhou University, published 2 research papers in Solar RRL on the progress in improving the stability and efficiency of perovskite tandem cells (see China Solar PV News Snippets).

POWERCHINA Announces Shortlisted Suppliers for 31 GW Module and 31 GW Inverter Procurement

Major power and energy project developer POWERCHINA has released the shortlist of candidates for its 2026 centralized framework procurement, covering 31 GW of PV modules and 31 GW of inverters.

The module tender includes 24 GW of TOPCon modules with 18 shortlisted companies at an average price of RMB 0.738/W, 3 GW of HJT modules with 6 companies at RMB 0.760/W, and 4 GW of BC modules with 8 companies at RMB 0.740/W.

The inverter procurement includes 8 GW of inverter-step-up integrated units (≥3,125 kW) with 6 shortlisted companies at RMB 12.23/W, 20 GW of string inverters (>300 kW, AC ≥ 800 V) with 15 companies at RMB 16.94/W, and 3 GW of string inverters (10-150 kW, AC 380 V) with 8 companies at RMB 3.38/W.

POWERCHINA recently fully grid-connected the Xiaojinchuan River Basin project in Sichuan, combining 160 MW of PV, 195 MW of hydropower, and a 16 MW/32 MWh energy storage system (see China Solar PV News Snippets).

Skyworth PV has signed a strategic cooperation agreement with Jingdong Property to collaborate on industrial park PV, warehousing integration, and overseas expansion.

Skyworth PV and Jingdong Property to Jointly Develop PV + Warehousing Projects

Skyworth PV has signed a strategic cooperation agreement with Jingdong Property to collaborate on industrial park PV, warehousing integration, and overseas expansion.

Jingdong Property, a subsidiary of JD Group, provides infrastructure construction and asset management services. The 2 companies will focus on PV project development across North, South, and East China. In 2025, they completed a 17.4 MW distributed PV project at the JD (Changzhou) Smart Industrial Park, using 120,000 m² of rooftop space to supply electricity for warehouse lighting and automated sorting systems. Earlier this month, Jingdong Property signed a strategic cooperation agreement with TCL Industries to develop commercial and industrial (C&I) distributed PV projects at various JD Logistics parks (see China Solar PV News Snippets).

The Skyworth-Jingdong partnership will continue to expand PV deployment in logistics and industrial park infrastructure.

Earlier this year, Skyworth PV’s parent company, Skyworth Group, announced its spin-off plans, listing Skyworth PV separately on the Main Board of the Hong Kong Stock Exchange (see China Solar PV News Snippets).

Hopewind Posts 32% YoY Adjusted Net Profit Growth for FY2025

PV inverter and wind converter manufacturer Hopewind reported FY2025 operating revenue of RMB 4.17 billion, up 11.64% year-on-year (YoY), while adjusted net profit reached RMB 524.93 million, increasing 32.34% YoY.

For the year, PV inverter sales fell 22.52% to 47,726 units, while wind converter sales rose 35.78% to 6,193 units. The company produced 7,341 MW (7.34 GW) of PV inverters in 2025, with a capacity utilization rate of 61.2%.

Fengfan Power Plans to Transfer 60% Stake in Wafer Manufacturing Subsidiary

Fengfan Power plans to transfer its 60% equity stake in its solar wafer subsidiary, Jingying Solar, through a pre-listing on the Jiangsu Equity Exchange.

Jingying Solar’s revenues for the first 9 months of 2025 totaled RMB 348 million, amounting to a net loss of RMB 96.32 million. Fengfan Power said the equity transfer will help it focus on its core power tower and steel structure businesses and preserve the value of state-owned assets.

The pre-listing is intended to solicit potential investors, with the final buyer and transaction price yet to be determined. It added that the current pre-listing serves solely as a preliminary disclosure of information to solicit potential transferees, with the final counterparty and transaction price yet to be determined.
